Is there a difference in dynamic range between film and digital?

Question

Is there a difference in dynamic range between film and digital?

Answer

The following article is an excellent comparison of the dynamic range differences of film and digital. It is a few years old, so it is a bit out of date, but the underlying theory is basically the same with modern gear. It has a lot of empirical data, and the conclusions are pretty interesting:

It should be noted that this article lacks some information about film. While digital does have good dynamic range in comparison to film in general, film does tend to edge out digital when it comes to highlights. Some empirical data is also missing due to the fact that the film images were scanned, which results in some loss of dynamic range and detail.
